The invention comprises at bar inning the construction horoimmltor (lvsorihod and claimed.

These Wobs or ribs m'o out of parallelism in. order to provnlo grinning moliots or nnrlmrs 8. es in tho cement. 'lhi irre-gulmity oi the .(i s may beoom'oniontly 1 onrod. by musing certain ribs to npprmir-h m'l i other at inlor vsls, such as by list i nn ngr tho Inn at the points 3, in such :1 nmnni-k as o (nus-o two oi the ribs to come In contact, its at l nnrl the opposite l two to come in contnot at This forms in two opposito i'in'os oi tho hnr n sm'zos of pockets o into which tho amount lills ancll thorohiro proviehw it o'ooii nnchomgo.
